I got the 6/8 for my 8 year old, he is also about 51" tall, and it fit him perfectly.

I think you should go for 8-10 size. The suit has straps at ankle and elastic at wrist place. So little bigger size will not be a problem. I ordered 10-12 size for my 8 year old and it's perfect for him.

My son too is 6"4", 175 lbs. and it was long enough in the arms and at the bottom.We usually order tall sizes so I was taking a chance in ordering this. It was long enough in the arms and in the length!

I'm 5'8" and I got a small 2", it's a little bigger than regular small. You might consider. Even though I don't like big clothes, he might fit in a regular medium, all depend on how he likes to wear his clothes.

My son is 8 years old & wears a size 7-8, it fit fine. My son is tall, the pants were a little short. No problem, I just made sure he wore black socks.

My son is 8 years old and in a size 6 that fits. He is super skinny though (normal height). If you get a 10 he can grow into it but it might be a bit big. An 8 would probably fit but he might be out of it quickly. I think my son weighs around 50 pounds?

Hmmm i purchased the size 6 im pretty stocky broad shoulders muscular arms i think a medium will be fine sounds like hes pretty leanmedium build but consider room for movement. I recommend a large but the store is pretty good about exchange.

It was off for my purchase. My son is 5'8", 130 lbs. The suggested size was too short for him. Or, he has abnormally long legs.

I would recommend 21 or 22 inches. When i was looking for my boys i investigated sizes and i remember that for 5-8 normally thats the size used. Hope this helps

My son is seven. He is 62" tall. They fit him well with some room for growth. It looks like this set will serve him well for at least a few more years. I do not know how much bigger the next size up is, but maybe knowing the size of my son in relation to the size of your child can help you decide which size to purchase. It is a nice set. Good luck!

Both of my boys are thin. My 8yr old wears a 7/8 slim. I got him the small and we pull the shoulders tight and it works. My 9 these old wears an 8/10 and wears the med comfortably.

My son is 10 and wears the medium and he is of average size for his age. Unless your 7 year old is tall for his age I would suggest a small.

my husband is 5'6 and 160 pounds and got the small/medium. It's perfect for him. Note that my 4'6 son is 92 pounds. It fits him except for the small harness which hooks to tree is loose. I would suggest you go to the larger size

You probably need to go with a 1/2 size, especially for the 7 year old. Maybe even a 3/4 for the 10 year old. I guess it also depends on how tall/big your boys are. My daughter is 5 (average height) and she is using a 1/4 size. I am NOT an expert by the way.
